The impact of bilingualism on the microstructure of the white matter pathways related to language processing is assessed in elementary school children by magnetic resonance diffusion tensor imaging (MR-DTI). Forty children, 8-11 years old, subdivided into 3 different groups (15 simultaneous bilinguals, 15 sequential bilinguals and 10 monolinguals), were scanned. The hypothesis was that the star...

We propose a uniform solution based on Pomset Logic to several diierent syntactic phenomena in Natural Languages, and in particular topicalization, relative clauses, interrogative clauses, extraposi-tion, discontinuous constituents and cliticization. We show that Pomset Logic is expressive enough to describe all the linguistic transformations due to these phenomena, in the sense that all transf...

A group is finitely axiomatizable (FA) in a class C if it can be determined up to isomorphism within by sentence the first-order language of theory. We show that profinite groups various kinds are FA groups, or pro- p for some prime p. Both algebraic and model-theoretic methods developed purpose. Reasons why certain cannot also discussed.

Auditory verbal hallucinations (AVH) is a common and stressful symptom of schizophrenia. Disrupted connectivity between frontal and temporo-parietal language areas, giving rise to the misattribution of inner speech, is speculated to underlie this phenomenon. Disrupted connectivity should be reflected in the microstructure of the arcuate fasciculi (AF); the main connection between frontal and te...

BACKGROUND AND PURPOSE Our aim was to improve our understanding of the subinsular white matter microstructural asymmetries in healthy right-handed subjects. Structural brain asymmetries could be related to functional asymmetries such as hemisphere language dominance or handedness. Besides the known gray matter asymmetries, white matter asymmetries could also play a key role in the understanding...

Decidability of the Star Problem, the problem whether the language IP is recognizable for a recognizable language IP, remains open. We slightly generalize the problem and show that then its decidability status depends strongly on the assumptions considering the trace monoid and niteness of IP. More precisely, we show that for nite set IP fA; Bg fCg and recognizable IR it is decidable whether IP...
